UNITED STATES PATENT OFFICE LOUIS FAVERIO, OF WESTERLY, RHODE ISLAND,ASSIGNOR TO WYOKOFF, SEAMANS & BENEDICT, OF ILION, NEW YORK, ACORPORATION OF NEW YORK.

TYPE-WRITING- MACHINE.

To all whom it may concern:

Be it known that 1, LOUIS FAvERIo, a citizen of the United States, andresident of Vesterly, in the county of Washington and State of RhodeIsland, have invented certainnew and useful Improvements in Type WritingMachines, of which the following is a specification.

My invention relates to typewriting machines and more particularly toline spacing mechanisms and one object of my invention is to providesimple and efficient means of the character specified.

Another object of my invention is to provide a construction in which aline spacing hand lever is situated at or near one end of the platen andthe line spacing devices controlled thereby are situated at the otherend of the platen.

A further object of my invention is to provide a construction in which asingle movement of a hand lever is effective to move the carriage to theright and to effect a line spacing movement of the platen.

A still further object of my invention is to provide a construction inwhich said line spacing hand lever may be employed to lift the carriage.

To the above and other ends which will hereinafter appear, my inventionconsists of the features of construction, arrangements of parts andcombinations of devices to be hereinafter described and claimed.

In the accompanying drawings wherein like reference characters representcorresponding parts in the different views, Figure 1 is a fragmentaryend elevation of the upper portion of a typewriting machine embodying myinvention. Fig. 2 is a front elevation of the carriage shown in Fig. 1.Fig. 3 is a fragmentary detail plan view showing the hand lever, aportion of the platen frame or carriage and a portion of the connectingrod. Fig. 4 is a detail fragmentary perspective view of a carriage withthe features of my invention applied thereto.

1 have shown my invention in connection with a No. 6 Remingtontypewriting machine to which the devices of my invention can be readilyapplied without making any material changes in the construction of thatmachine, though it should be understood that the invention may beemployed in different styles of typewriting machines.

The corner posts 1 of the frame support a Specification of LettersPatent.

top plate 2 from which upwardly projecting lugs 3 extend. These lugssupport a guide rail or track 4 with which rollers 5, pivoted to thecarriage truck 6, cooperate. The platen frame is rectangular andcomprises end bars 7, a front cross bar 8 and a rear cross bar 9. Pivots10 connect the platen frame to links 11 which are pivoted at their lowerends 12 to the truck. A platen 13 is provided with a platen shaft 141journaled in bearings in the end bars 7 of the platen frame. A roller 15is carried by the front cross bar 8 of the platen frame and bears upon ashift rail 16 carried by vibratory arms or levers l? to effect a changein the case position of the platen. A line spacing ratchet wheel 18 issecured to the platen at the right hand end thereof and a roller detent19 cooperates with the line spacing ratchet wheel in the usual manner.An upright post or standard 20 projects from the right-hand end bar 7 ofthe platen frame and is provided with an inwardly projecting stop pin 21to limit the feed movement of a line spacing pawl 22 and to jam the pawland prevent an overthrow of the platen. The line spacing pawl isconnected by a horizontal pivot 23 to an actuating lever 2i which isconnected to a depending bracket arm 25 on the platen frame by ahorizontal pivot 26 which is in the nature of a shouldered headed screw.A forwardly extending arm 27 projects from this lever arm so as to forma bell crank lever. A second bell crank lever 28 is connected to thebracket 25 by a headed shouldered screw 29 so that the piv otal axis ofthe bell crank lever 28 is at right angles, or at substantially rightangles, to the pivotal axis of the lever 24. The horizontally disposedarm of the bell crank lever 28 extends beneath the arm 27 of the lever24. for cooperation therewith and the upright arm of the bell crank 28is pivoted at 30 to a rod 31 which is connected at its opposite end to ahand lever 32 which may be situated at any convenient point along thefront of the carriage, but which I prefer to mount at or near theopposite or left-hand end of the platen. The connection between thepivot rod and the hand lever is effected by a pivot screw 33. The handlever itself is pivoted to the front cross bar 8 of the platen frame bya headed shouldered screw 34 so as to receive a horizontal pivotalmovement around its pivot. An upwardly projecting arm 35 is formed onthe bracket 25 and pivotally supports a regulating device 36 providedwith three contact faces 37, 3S and 39 and with a handle or finger piecea0 by which it may be turned on its pivot 41 so as to bring any of thethree faces to a position where it will cooperate with a depending arm42 on the line spacing pawl. The device 36 has three notches 4C3, i tand 45 with which a detent spring 46 cooperates, the spring beingsecured by a screw 4:7 to the bracket arm It will be understood that theregulating device 36 limits the return movement of the line spacing pawland its actuating lever 24-, and determines the extent of line spacingmovement to be transmitted to the platen. The line spacing pawl andlever 24 are restored to normal position by the usual spring 48, whereasthe lever 28, connecting rod 31 and handle 32 are acted upon by a weakerspring 18 which holds the horizontal arm of the bell crank 28 up againstthe lever arm 27. The normal position of the hand lever 32 depends onthe adjustment of the device 36. Thus, it will be understood that whenone of the three contact faces of the device 36 is brought intocooperation with the line spacing pawl, the hand lever 32 will. normallybe in the position indicated by the dot and dash line a in Fig. 3,whereas under another adjustment of said device the hand lever willnormally be in the position indicated by the dot and dash line b andunder a third adjustment of the device 36 the hand lever will normallybe in the full line position. In each instance, however, the hand leveris adapted to swing in a horizontal plane around its pivot to a positioncorresponding to that indicated by the dotted line a in Fig. 3.

The hand lever 32 replaces the finger piece ordinarily employed in theNo. 6 Remington machine for lifting the platen frame and which issituated at about the same point that the lever 32 occupies in thepresent construction. The hand lever 32 is, as before stated, free toswing horizontally around its pivot but cannot move verticallyindependently of the platen frame so that the hand lever is adapted toswing the platen frame back to expose the writing. A single movement ofthe hand lever from left to right under any adjustment of the device 36is effective not only to produce a line spacing movement of the pawl 22but also to move the carriage to the right to begin a new line. Theconstruction is such, furthermore, that the line spacing movement andrestoration of the carriage can be effected by a single movement of theleft hand without moving the right hand from the keyboard of themachine. The line spacing operation is preferably effected before thecarriage is moved to the right, although the resistance offered to theturning of the platen may be such that the line spacing is not effecteduntil the ca-r ria ,"e has reached the limit of its movement to theright when the positive resistance offered to a further movement of thecarriage to the right will render the hand lever effective to actuatethe line spacing mechanism.

From the foregoing description it will be seen that the line spacingpawl 22 moves in a plane that extends transversely of the platen andmoves fore and aft of the machine, whereas the hand lever 32 swings onits pivot in a direction at right angles to the plane of movement of thepawl and that the intermediate connections between the pawl and handlever change the direction of power transmitted from said lever to thepawl.

In order to line space without moving the carriage, the hand lever 32may be given a turning movement about its pivot insteadof being pushedby a single impulse toward the right. i

If desired the usual hand lever of the No. 6 Remington machine may beused instead of the lever 24, thus affording an additional hand lever atthe other end of the carriage.

Various other changes may be made without departing from the spirit andscope of my invention.

What I claim as new and desire to secure by Letters Patent, is

1. In a typewriting machine, the combination of a carriage, a platencarried thereby, a line spacing ratchet wheel connected with the platenat one end thereof, a pawl cooperative with said ratchet wheel, anactuating lever pivoted to the carriage and to which said pawl ispivoted, a bell crank lever pivoted to the carriage and cooperative withsaid actuating lever, a hand actuated lever pivoted to the carriage andsituated at or near the opposite end of'the platen, and a connecting rodbetween said bell crank lever and hand lever.
